Feature/support for unity licensing server linux (#468)

* Initial support for adding a UNITY_LICENSING_SERVER parameter to build parameters

* Test to figure out what the working directory is of current bash script

* Outputting current directory and using $ACTION_FOLDER

* Add resources folder to mounted docker volumes. Used by activation script to copy over template file for unity licensing server

* use awk instead of sed due to http characters breaking syntax

* mkdir for unity config

* Add -p flag to mkdir so parents are also created if missing

* Initial work on returning floating license when using licensing server

* Checking licensing server first for now, since serial is always set

* Parse and save acquired floating license for use for returning after build

* Clean up duplicate commands in activate.sh

* Fixed running string as command, use it as input instead

* Fixed cloud runner tests failing when using a ssh remote.

* Clean up of test files and unnecessary logging

* Moved process of generating services-config.json file from platform specific activate scripts to typescript

* Fixed path
